Method and device to actuate specialized intervention equipment in a drilled well having at least one section highly slanted with respect to a vertical line

Abstract

A method and device for actuating specialized equipment in a drilled well having at least one well zone, sharply slanted with respect to the vertical, and with the drilled well having at least one tubular control column along which operating equipment as remotely installed. A control member is introduced in to the first tubular control column, with a cable being attached at one end of the control member. The control member is lowered into the first tubular control column by a downward hydraulic pumping, and the cable is paid into the tubular pipe from the surface. The control member is raised by pulling on the cable from the surface and the specialized operating equipment is selectively maneuvered while the control member is flush against the equipment in a downward or upward travel of the control member in the drilled well.

       3. Method for operating specialized equipment according to one of claims 1 or 2, wherein the specialized equipment includes valve means for producing fluid from the geological formation traversed by the well, and wherein the method further comprises the steps of: operating said valve means by said control member,   causing the fluid to flow in said first tubular control column, and   producing said fluid at the surface in a a production column connected at a bottom end thereof with a bottom end of said tubular control column.   
     
     
       4. Device for operating specialized manipulation equipment in a drilled well having at least one well zone sharply slanted with respect to the vertical, said drilled well having a least one first tubular pipe means along which said specialized manipulating equipment is remotely installed, a control member introduced into said first tubular pipe means, cable means connected to one end of said control member, downward hydraulic pumping means for moving said control member in said tubular pipe means, means for paying the cable means into the tubular pipe means, means for pulling on the cable means from the surface, and means provided on said control member for allowing a selective control of at least some of said specialized manipulating equipment while bypassing other of said specialized manipulating equipment when the control member presses flush against said specialized manipulating equipment as the control member is raised or lowered in the drilled well. 
     
     
       5. Device for operating specialized manipulating equipment according to claim 4, wherein said means for allowing includes at least one key sliding bolt means for cooperating with an operating seat means of at least one item of the specialized manipulating equipment, said at least one key sliding bolt means is provided at a circumference of the control member, and said operating seat means has a shape matching a shape of said key sliding bolt means. 
     
     
       6. Device for operating specialized manipulating equipment according to claim 5, further comprising means for interlocking said key sliding bolt means with the operating seat means of said equipment, means for driving said specialized manipulating equipment by said control member at a time of interlocking, and means for disengaging said key sliding bolt means once an operation by the control member has been carried out. 
     
     
       7. Device for operating specialized manipulating equipment according to claim 6, wherein said first tubular pipe means includes a tubular control column, the specialized manipulating equipment includes valve means for producing fluid from geological formations traversed by the well, and a second pipe means including a production column connected at a bottom end thereof with a bottom end of said tubular control column. 
     
     
       8. Device for operating specialized manipulating equipment according to claim 7, further comprising a pump means disposed in the production column. 
     
     
       9. Device for operating specialized manipulating equipment according to claim 8, further comprising means for circulating fluid through the control member once a certain threshold of pull on said cable means has been exceeded, wherein the fluid circulation through said control member is effected from an upper part of the control member connected to the cable means to a lower part of the control member. 
     
     
       10. System for producing fluid from a geological formation traversed by a drilled well comprising a device according to claim, 9, comprising sealing means for dividing the well into several production zones separated and isolated from each other, and with at least one valve being disposed in the one production zone. 
     
     
       11. System for producing fluid from a geological formation, according to claim 10, wherein said sealing means include packer type seals.
